oles) /time(seconds)"Now the concentration is given by "moles/liter". And the moles are "mass(gram)/molecular mass(grams)". So the moles are directly proportional to the mass of the substance. So the ...

The answer to this question is fairly easy to put into words. A polymer is a large molecule of high molecular mass, formed by the joining together, or polymerization, of a large number of molecules of ... ed monomers. That brings up another question, what is a monomer? A monomer is a molecule with a low molecular weight. (chem 8th pgs. G-9, G-11) In the year 1827 a scientist by the name of Jons Jakob B ...

cause the metal in the railroad tracks has a higher heat capacity than air. For a substance, if the molecular mass, the speed of sound through that substance, and temperature of a gas is known, the re ... s available to it. [1] Each degree of freedom of a molecule can be described as a way that the intramolecular forces of molecule can cause movement in the molecule. This movement is a direct form of s ...

mically and physically from its parent atoms.In this lab, we realized that the stronger the intermolecular forces are, the smaller the delta t is. This is because it takes longer to break these bo ... e is a greater dispersion force, and therefore a lower delta t. Butanol and pentane have a similar molecular weight, but butanes delta t is lower than pentanes delta t. This is because butanol h ...
